Experimental studies on the performance and emission characteristics of a compression ignition engine fuelled with jatropha oil methyl ester

Journal of Mechanical Engineering and Sciences, 2018
In this work, biodiesel obtained from jatropha seedsare used as alternative fuel to dieselvin stationary diesel engines. The oil obtained from the jatropha seeds are trans-esterified to get biodiesel. The biodiesel obtained has good ignition ability due

Trade-off between soot and NO emissions during enclosed spray combustion of jet fuel

Scientific Reports
Aviation emissions of soot and nitrogen oxides are strictly regulated as they adversely impact human health and the environment. Jet fuel combustion conditions that decrease one pollutant concentration increase the other. Although it is not impossible to

Autonomous X‐Ray Fluorescence Mapping for Nanoscale Chemical Speciation of Fine Particulate Matter

Advanced Intelligent Discovery, EarlyView.
We present X‐AutoMap, an autonomous X‐ray fluorescence mapping framework that integrates real‐time analysis with rule‐based computer vision to selectively target chemically relevant regions. By avoiding background‐dominated areas, the method reduces acquisition time by fourfold while enabling accurate particle‐level speciation.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
